FIRE SAFETY TIPS

Follow safety rules and prevent hazardous situations: 1) Use smoking materials properly.

Never smoke in bed. 2) Keep matches or lighters away from children; 3) Store flammable

materials in proper containers; 4) Keep electrical appliances in good condition and don’t

overload electrical circuits; 5) Keep stoves, barbecue grills, fireplaces and chimneys grease-

and debris-free; 6) Never leave anything cooking on the stove unattended; 7) Keep portable

heaters and open flames, like candles, away from flammable materials; 8) Don’t let rubbish

accumulate.

Keep alarms clean, and test them weekly. Replace alarms immediately if they are not

working properly. Smoke Alarms that do not work cannot alert you to a fire. Keep at least

one working fire extinguisher on every floor, and an additional one in the kitchen. Have fire

escape ladders or other reliable means of escape from an upper floor in case stairs are

blocked.

BEFORE YOU INSTALL THIS SMOKE ALARM

Important! Read “Recommended Locations for Smoke Alarms” and “Locations to Avoid

for Smoke Alarms” before beginning. This unit monitors the air, and when smoke reaches

its sensing chamber, it alarms. It can give you more time to escape before fire spreads.

This unit can ONLY give an early warning of developing fires if it is installed, maintained and

located where smoke can reach it, and where all residents can hear it, as described in this

manual. This unit will not sense gas, heat, or flame. It cannot prevent or extinguish fires.

Understand The Different Type of Smoke Alarms

Battery powered or electrical? Different Smoke Alarms provide different types of

protection. See “About Smoke Alarms” for details.

Know Where To Install Your Smoke Alarms

Fire Safety Professionals recommend at least one Smoke Alarm on every level of your

home, in every bedroom, and in every bedroom hallway or separate sleeping area. See

“Recommended Locations For Smoke Alarms” and “Locations To Avoid For Smoke

Alarms” for details.

Know What Smoke Alarms Can and Can’t Do

A Smoke Alarm can help alert you to fire, giving you precious time to escape. It can

only sound an alarm once smoke reaches the sensor. See “Limitations of Smoke

Alarms” for details.

Check Your Local Building Codes

This Smoke Alarm is designed to be used in a typical single-family home. It alone will not

meet requirements for boarding houses, apartment buildings, hotels or motels. See “Special

Compliance Considerations”

for details.

All First Alert

and BRK

Smoke Alarms conform to regulatory requirements,

including UL217 and are designed to detect particles of combustion. Smoke parti-

cles of varying number and size are produced in all fires.

Ionization technology is generally more sensitive than photoelectric technology

at detecting small particles, which tend to be produced in greater amounts by

flaming fires, which consume combustible materials rapidly and spread quickly.

Sources of these fires may include paper burning in a wastebasket, or a grease

fire in the kitchen.

Photoelectric technology is generally more sensitive than ionization technology at

detecting large particles, which tend to be produced in greater amounts by smol

dering fires, which may smolder for hours before bursting into flame. Sources of

these fires may include cigarettes burning in couches or bedding.

For maximum protection, use both types of Smoke Alarms on each level and in every

bedroom of your home.

ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Smoke

Alarm is installed before removing it from the mounting bracket. Failure to turn off

the power first may result in serious electrical shock, injury or death.

• This unit will not alert hearing impaired residents. It is recommended that

you install special units which use devices like flashing strobe lights to alert

hearing impaired residents.

• Installation of this unit must conform to the electrical codes in your area;

Articles 210 and 300.3 (B) of NFPA 70 (NEC), NFPA 72, NFPA 101; ICC; SBC

(SBCCI); UBC (ICBO); NBC (BOCA); OTFDC (CABO), and any other local or

building codes that may apply. Wiring and installation must be performed by

a licensed electrician. Failure to follow these guidelines may result in injury

or property damage.

• This unit must be powered by a 24-hour, 120V AC pure sine wave 60 Hz

circuit. Be sure the circuit cannot be turned off by a switch, dimmer, or

ground fault circuit interrupter. Failure to connect this unit to a 24-hour

circuit may prevent it from providing constant protection. Unit may be

connected to an arc fault circuit interrupter.

• This Smoke Alarm must have AC or battery power to operate. If the AC

power fails, battery back-up will allow the alarm to sound for at least 4

minutes. If AC power fails and the battery is weak, protection should last for

up to 7 days. If AC power fails and the battery is dead or missing, the alarm

cannot operate.

• Never disconnect the power from an AC powered unit to stop an unwanted

alarm. Doing so will disable the unit and remove your protection. In the case

of a true unwanted alarm open a window or fan the smoke away from the

unit. The alarm will reset automatically when it returns to normal operation.

Never remove the batteries from a battery operated unit to stop an unwanted

alarm (caused by cooking smoke, etc.). Instead open a window or fan the

smoke away from the unit. The alarm will reset automatically.

• Connect this unit ONLY to other compatible units. See “How To Install This

Smoke Alarm” for details. Do not connect it to any other type of alarm or

auxiliary device. Connecting anything else to this unit may damage it or

prevent it from operating properly.

• The battery compartment resists closing unless a battery is installed. This

warns you the unit will not operate under DC power without a battery.

• Do not paint over the unit. Paint may clog the openings to the sensing

chamber and prevent the unit from operating properly.

IMPORTANT! PLEASE READ CAREFULLY AND SAVE

This user’s manual contains important information about your Smoke Alarm’s

operation. If you are installing the Smoke Alarm for use by others, you must leave this

manual — or a copy of it — with the end user.

The Mounting Bracket:

To remove the mounting bracket from the Smoke Alarm base,

hold the Smoke Alarm base firmly and twist the mounting

bracket counterclockwise. The mounting bracket installs onto

the junction box. It has a variety of screw slots to fit most boxes.

The Power Connector:

The power connector plugs into a power input block on the

Smoke Alarm. It supplies the unit with AC power.

• The black wire is “hot.”

• The white wire is neutral.

• The orange wire is used for interconnect.

If you need to remove the power connector, insert a flat screwdriver

blade between the power connector and the security tab inside the

power input block. Gently pry back the tab and pull the connector free.

The basic installation of this Smoke Alarm is similar whether you want to install one

Smoke Alarm, or interconnect more than one Smoke Alarm. If you are interconnecting

more than one Smoke Alarm, you MUST read “Special Requirements For Interconnected

Smoke Alarms” below before you begin installation.

ELECTRICAL SHOCK HAZARD. Turn off power to the area where you will install this

unit at the circuit breaker or fuse box before beginning installation. Failure to turn off

the power before installation may result in serious electrical shock, injury or death.

1. Using wire nuts, connect the power connector to the household wiring.

Improper wiring of the power connector or the wiring leading to the power

connector will cause damage to the Alarm and may lead to a non-functioning

Alarm.

2. Remove the mounting bracket from the base, and attach it to the junction box.

3. Plug the power connector into the back of the Smoke Alarm.

4. Position the base of the Smoke Alarm over the mounting bracket and turn. The

Alarm will remain secure over a wide rotation range to allow for perfect alignment.

When wall mounting, this will allow fine-tuning on the positioning to compensate

for misaligned wall studs and to keep the wording level. The Alarm can be positioned

over the bracket every 120°. Rotate the Alarm until aligned properly.

5. Check all connections.

ELECTRICAL SHOCK HAZARD. Do not restore power until all Smoke Alarms are

completely installed. Restoring power before installation is complete may result in

serious electrical shock, injury or death.

6. Make sure the Smoke Alarm is receiving AC power. Under normal operation, the

Green power indicator light will shine continuously.

7. If the Green power indicator light does not light, TURN OFF POWER TO THE

JUNCTION BOX and recheck all connections. If all connections are correct and

the Green power indicator still does not light when you restore the power, the unit

should be replaced immediately.

8. Single Station Alarms: Test each Smoke Alarm. Press and hold the Test/Silence

button until the unit alarms.

Interconnected Alarms: Press and hold the Test/Silence button until the unit alarms.

All interconnected Alarms should sound. The other Alarms sounding only tests the

interconnect signal between Alarms. It does not test each Alarm’s operation. You

must test each Alarm individually to check if the Alarm is functioning properly.

If any unit in the series does not alarm, TURN OFF POWER and recheck connections.

If it does not alarm when you restore power, replace it immediately.

SPECIAL REQUIREMENTS FOR INTERCONNECTED SMOKE ALARMS

• Failure to meet any of the above requirements could damage the units and

cause them to malfunction, removing your protection.

• AC and AC/DC Smoke Alarms can be interconnected. Under AC power, all

units will alarm when one senses smoke. When power is interrupted, only

the AC/DC units in the series will continue to send and receive signals.

AC powered Smoke Alarms will not operate.

Interconnected units can provide earlier warning of fire than stand-alone units, especially

if a fire starts in a remote area of the dwelling. If any unit in the series senses smoke, all

units will alarm. To determine which Smoke Alarm initiated an alarm, see table:

During an Alarm:

On Initiating Alarm(s) Red LED(s) flashes (flash) rapidly

On All Other Alarms Red LED is Off

After an Alarm (Latching):

On Initiating Alarm(s) Green LED(s) On for 2 seconds/Off for 2 seconds

On All Other Alarms Green LED(s) On, Red LED(s) is Off

Compatible Interconnected Units

Interconnect units within a single family residence only. Otherwise all households will

experience unwanted alarms when you test any unit in the series. Interconnected units

will only work if they are wired to compatible units and all requirements are met. This unit

LOCKING FEATURES

The locking features are designed to discourage unauthorized removal of the battery or alarm. It is not necessary to activate the locks in single-family households where

unauthorized battery or alarm removal is not a concern.

This alarm has two separate locking features: one to lock the battery compartment, and the other to lock the Smoke Alarm to the mounting bracket. This alarm is shipped

from the factory with the battery drawer locked because it features a 10 year battery backup. Under normal conditions you should not have to replace the battery for the life

of the alarm. If you need to replace the battery follow the UNLOCK THE BATTERY COMPARTMENT instructions below. Re-lock Battery Compartment if desired.

Tools you will need: • Needle-nose pliers or utility knife • Standard Flathead screwdriver.

Both locking features use locking pins, which are molded into the mounting bracket. Using needle nose pliers or a utility knife, remove one or both pins from the

mounting bracket, depending on how many locking features you want to use.

To permanently remove either lock insert a flathead screwdriver between the locking pin and the lock, and pry the pin out of the lock.

WEEKLY TESTING

NEVER use an open flame of any kind to test this unit. You might accidentally damage

or set fire to the unit or to your home. The built-in test switch accurately tests the

unit’s operation as required by Underwriters Laboratories, Inc. (UL).

DO NOT stand close to the Alarm when the horn is sounding. Exposure at close range

may be harmful to your hearing. When testing, step away when horn starts sounding.

It is important to test this unit every week to make sure it is working properly. Using

the test button is the recommended way to test this Smoke Alarm. Press and hold the

test button on the cover of the unit until the alarm sounds (the unit may continue to alarm

for a few seconds after you release the button). If it does not alarm, make sure the unit is

receiving power and test it again. If it still does not alarm, replace it immediately. During

testing, you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.

When testing a series of interconnected units you must test each unit individually.

Make sure all units alarm when each one is tested.

REGULAR MAINTENANCE

This unit has been designed to be as maintenance-free as possible, but there are a few

simple things you must do to keep it working properly.

• Test it at least once a week.

• Clean the Smoke Alarm at least once a month; gently vacuum the outside of the

Smoke Alarm using your household vacuum’s soft brush attachment. Test the Smoke

Alarm. Never use water, cleaners or solvents since they may damage the unit.

• If the Smoke Alarm becomes contaminated by excessive dirt, dust and/or grime, and

cannot be cleaned to avoid unwanted alarms, replace the unit immediately.

• Relocate the unit if it sounds frequent unwanted alarms. See “Locations To Avoid For

Smoke Alarms” for details.

• When the battery back-up becomes weak, the Smoke Alarm will “chirp” about once

a minute (the low battery warning). This warning should last 7 days, but you should

replace the battery immediately to continue your protection.

Choosing a replacement battery:

Your Smoke Alarm requires one standard 9V battery. The following batteries are acceptable

as replacements: Duracell #MN1604, (Ultra) #MX1604; Eveready (Energizer) #522, Eveready

(Energizer) #1222. You may also use a Lithium battery like the Ultralife U9VL-J, U9VL-J-P

for longer service life between battery changes. These batteries are available at many

local retail stores.

• Always use the exact batteries specified by this User’s Manual. DO NOT use

rechargeable batteries. Clean the battery contacts and also those of the device

prior to battery installation. Install batteries correctly with regard to polarity

(+ and -).

• Please dispose of or recycle used batteries properly, following any local

regulations. Consult your local waste management authority or recycling

organization to find an electronics recycling facility in your area. DO NOT

DISPOSE OF

BATTERIES IN FIRE. BATTERIES MAY EXPLODE OR LEAK.

• Keep battery out of reach of children. In the event a battery is swallowed,

immediately contact your poison control center, your physician, or the National

Battery Ingestion hotline at 202-625-3333 as serious injury may occur

Actual battery service life depends on the Smoke Alarm and the environment in which it is

installed. All the batteries specified above are acceptable replacement batteries for this unit.

Regardless of the manufacturer’s suggested battery life, you MUST replace the battery

immediately once the unit starts “chirping” (the “low battery warning”).

WHAT TO DO IN CASE OF FIRE

• Don’t panic; stay calm. Follow your family escape plan.

• Get out of the house as quickly as possible. Don’t stop to get dressed or collect

anything.

• Feel doors with the back of your hand before opening them. If a door is cool, open

it slowly. Don’t open a hot door. Keep doors and windows closed, unless you must

escape through them.

• Cover your nose and mouth with a cloth (preferably damp). Take short, shallow breaths.

• Meet at your planned meeting place outside your home, and do a head count to make

sure everybody got out safely.

• Call the Fire Department as soon as possible from outside. Give your address, then

your name.

• Never go back inside a burning building for any reason.

• Contact your Fire Department for ideas on making your home safer.

Alarms have various limitations. See “Limitations of Smoke Alarms” for details.

IF THIS SMOKE ALARM SOUNDS

RESPONDING TO AN ALARM

During an alarm, you will hear a loud, repeating horn pattern: 3 beeps, pause,

3 beeps, pause.

• If the unit alarms and you are not testing the unit, it is warning you of a

potentially dangerous situation that requires your immediate attention.

NEVER ignore any alarm. Ignoring the alarm may result in injury or death.

• Never disconnect the AC power to quiet an unwanted alarm. Disconnecting

the power disables the Alarm so it cannot sense smoke. This will remove your

protection. Instead open a window or fan the smoke away from the unit.

The alarm will reset automatically.

• If the unit alarms get everyone out of the house immediately.

• ELECTRICAL SHOCK HAZARD: Attempting to disconnect the power connector

from the unit when the power is on may result in electrical shock, serious injury

or death.

When an interconnected system of AC powered units is in alarm, the alarm indicator light on

the unit(s) that initiated the alarm will blink rapidly. It will remain OFF on any remaining units.

If the unit alarms and you are certain that the source of smoke is not a fire—cooking smoke

or an extremely dusty furnace, for example—open a nearby window or door and fan the

smoke away from the unit. Use the Silence Feature to silence the alarm. This will silence the

alarm, and once the smoke clears the unit will reset itself automatically.

“LATCHING ALARM” INDICATOR

IF YOU SUSPECT A PROBLEM

Smoke Alarms may not operate properly because of dead, missing or weak batteries, a

build-up of dirt, dust or grease on the Smoke Alarm cover, or installation in an improper

location. Clean the Smoke Alarm as described in “Regular Maintenance,” and install a fresh

battery, then test the Smoke Alarm again. If it fails to test properly when you use the Test/

Silence button, or if the problem persists, replace the Smoke Alarm immediately.

• If you hear a “chirp” once a minute, replace the battery.

• If you experience frequent non-emergency alarms (like those caused by cooking

smoke), try relocating the Smoke Alarm.

• If the alarm sounds when no smoke is visible, try cleaning or relocating the

Smoke Alarm. The cover may be dirty.

• If the alarm does not sound during testing, make sure it is receiving AC power

from the household current.

Always discharge the branch circuit before servicing an AC or AC/DC Smoke Alarm.

First, turn off the AC power at the circuit breaker or fuse box. Next, remove the battery

from Smoke Alarms with battery back-up. Finally, press and hold the test button for

5-10 seconds to discharge the branch circuit.

Do not try fixing the alarm yourself – this will void your warranty!

If the Smoke Alarm is still not operating properly, and it is still under warranty, please see

“How to Obtain Warranty Service” in the Limited Warranty.

RECOMMENDED LOCATIONS FOR SMOKE ALARMS

Installing Smoke Alarms in Single-Family Residences

The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every

floor, in every sleeping area, and in every bedroom. In new construction, the Smoke Alarms

must be AC powered and interconnected. See “Agency Placement Recommendations” for

details. For additional coverage, it is recommended that you install a Smoke Alarm in all

rooms, halls, storage areas, finished attics, and basements, where temperatures normally

remain between 40˚ F (4.4˚ C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction

could keep smoke from reaching the Smoke Alarms.

More specifically, install Smoke Alarms:

• On every level of your home, including finished attics and basements.

• Inside every bedroom, especially if people sleep with the door partly or completely closed.

• In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit

in each. If a hall is more than 40 feet (12 meters) long, install a unit at each end.

• At the top of the first-to-second floor stairway, and at the bottom of the basement stairway.

Specific requirements for Smoke Alarm installation vary from state to state and from region

to region. Check with your local Fire Department for current requirements in your area. It is

recommended AC or AC/DC units be interconnected for added protection.

KEY:

The Latching Alarm Indicator is automatically activated after an Alarm is exposed to

alarm levels of smoke. After smoke levels drop below alarm levels, the green LED will be

On for 2 seconds/Off for 2 seconds, repeatedly. This feature helps emergency responders,

investigators, or service technicians identify which unit(s) in your home were exposed to

alarm levels of smoke after the condition has subsided. The Latching Alarm Indicator stays

ON until you reset it by pressing the Test/Silence button. The Latching Alarm Indicator is

also reset when AC and DC power is removed from the Alarm.

USING THE SILENCE FEATURE

The Silence Feature on this unit can temporarily quiet an unwanted alarm for up to 10 minutes.

The Silence Feature does not disable the unit—it makes it temporarily less sensitive

to smoke. For your safety, if smoke around the unit is dense enough to suggest a

potentially dangerous situation, the unit will stay in alarm or may re-alarm quickly.

If you do not know the source of the smoke, do not assume it is an unwanted alarm.

Not responding to an alarm can result in property loss, injury, or death. If the unit will

not silence and no heavy smoke is present, or if it stays in silence mode continuously,

it should be replaced immediately.

To silence Smoke Alarms in an interconnected series:

1. To silence multiple alarms in an interconnected series, you must press the Test/Silence

button on the unit(s) that initiated the alarm.

NOTE: The red LED on the initiating alarm will flash rapidly. The red LED will be Off on

all other non-initiating alarms. No audible sound will be heard. The unit will exit “silence

mode” in approximately 10 minutes.

2. While the unit is in “silence mode”, pressing and holding the Test/Silence button for

approximately 10 seconds will test the unit. After testing, the unit will re-enter “silence

• In air streams near kitchens. Air currents can draw cooking smoke into the sensing

chamber of a Smoke Alarm near the kitchen.

• In very damp, humid or steamy areas, or directly near bathrooms with showers.

Keep units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.

• Where the temperatures are regularly below 40˚ F (4.4˚ C) or above 100˚ F (37.8˚ C)

including unheated buildings, outdoor rooms, porches, or unfinished attics or

basements.

• In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the

stove or range. Clean a laundry room unit frequently to keep it free of dust or lint.

• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke away

from the unit, preventing it from reaching sensing chamber.

• In insect infested areas. Insects can clog openings to the sensing chamber and cause

unwanted alarms.

• Less than 12 inches (305 mm) away from fluorescent lights. Electrical “noise” can

interfere with the sensor.

• In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching the Smoke

Alarm.

AVOIDING DEAD AIR SPACES

“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To avoid dead air

spaces, follow the installation recommendations below.

On ceilings, install Smoke Alarms as close to the center of the ceiling as possible. If this is

not possible, install the Smoke Alarm at least 4 inches (102 mm) from the wall or corner.

For wall mounting (if allowed by building codes), the top edge of Smoke Alarms should be

placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line, below

typical “dead air” spaces.

On a peaked, gabled, or cathedral ceiling, install the first Smoke Alarm within 3 feet (0.9

meters) of the peak of the ceiling, measured horizontally. Additional Smoke Alarms may be

required depending on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for

details on requirements for sloped or peaked ceilings.

SPECIAL COMPLIANCE CONSIDERATIONS

This Smoke Alarm is suitable for use in apartments, condominiums, townhouses, hospitals,

day care facilities, health care facilities, boarding houses, group homes and dormitories

provided a primary fire detection system already exists to meet fire detection requirements

in common areas like lobbies, hallways, or porches. Using this Smoke Alarm in common

areas may not provide sufficient warning to all residents or meet local fire protection

ordinances/regulations.

This Smoke Alarm alone is not a suitable substitute for complete fire detection systems

in places housing many people—like apartment buildings, condominiums, hotels, motels,

dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group

homes of any kind. It is not a suitable substitute for complete fire detection systems in

warehouses, industrial facilities, commercial buildings, and special-purpose non-residential

buildings which require special fire detection and alarm systems. Depending on the building

codes in your area, this Smoke Alarm may be used to provide additional protection in

these facilities.

In new construction, most building codes require the use of AC or AC/DC powered Smoke

Alarms only. In existing construction, AC, AC/DC, or DC powered Smoke Alarms can

be used as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and

Signaling Code) and NFPA 101 (Life Safety Code), local building codes, or consult your

Fire Department for detailed fire protection requirements in buildings not defined as

“households”.

LIMITATIONS OF SMOKE ALARMS

Smoke Alarms have played a key role in reducing deaths resulting from home fires

worldwide. However, like any warning device, Smoke Alarms can only work if they are

properly located, installed, and maintained, and if smoke reaches the Alarms. They are not

foolproof.

Smoke alarms may not waken all individuals. Practice the escape plan at least twice a

year, making sure that everyone is involved – from kids to grandparents. Allow children to

master fire escape planning and practice before holding a fire drill at night when they are

sleeping. If children or others do not readily waken to the sound of the smoke alarm, or if

there are infants or family members with mobility limitations, make sure that someone is

assigned to assist them in fire drill and in the event of an emergency. It is recommended

that you hold a fire drill while family members are sleeping in order to determine their

response to the sound of the smoke alarm while sleeping and to determine whether they

may need assistance in the event of an emergency.

Smoke Alarms cannot work without power. Battery operated units cannot work if the

batteries are missing, disconnected or dead, if the wrong type of batteries are used, or if the

batteries are not installed correctly. AC units cannot work if the AC power is cut off for any

reason (open fuse or circuit breaker, failure along a power line or at a power station, electrical

fire that burns the electrical wires, etc.). If you are concerned about the limitations of battery

or AC power, install both types of units.

Smoke Alarms cannot detect fires if the smoke does not reach the Alarms. Smoke from

fires in chimneys or walls, on roofs, or on the other side of closed doors may not reach the

sensing chamber and set off the Alarm. That is why one unit should be installed inside each

bedroom or sleeping area—especially if bedroom or sleeping area doors are closed at night—

and in the hallway between them.

Smoke Alarms may not detect fire on another floor or area of the dwelling. For example,

a stand-alone unit on the second floor may not detect smoke from a basement fire until the

fire spreads. This may not give you enough time to escape safely. That is why recommended

minimum protection is at least one unit in every sleeping area, and every bedroom on every

level of your dwelling. Even with a unit on every floor, stand-alone units may not provide as

much protection as interconnected units, especially if the fire starts in a remote area. Some

safety experts recommend installing interconnected AC powered units with battery back-up

(see “About Smoke Alarms”) or professional fire detection systems, so if one unit senses

smoke, all units alarm. Interconnected units may provide earlier warning than stand-alone

units since all units alarm when one detects smoke.

Smoke Alarms may not be heard. Though the alarm horn in this unit meets or exceeds

current standards, it may not be heard if: 1) the unit is located outside a closed or partially

closed door, 2) residents recently consumed alcohol or drugs, 3) the Alarm is drowned out

by noise from stereo, TV, traffic, air conditioner or other appliances, 4) residents are hearing

impaired or sound sleepers. Special purpose units, like those with visual and audible alarms,

should be installed for hearing impaired residents.

Smoke Alarms may not have time to alarm before the fire itself causes damage,

injury, or death, since smoke from some fires may not reach the unit immediately.

Examples of this include persons smoking in bed, children playing with matches, or

fires caused by violent explosions resulting from escaping gas.

Smoke Alarms are not foolproof. Like any electronic device, Smoke Alarms are made of

components that can wear out or fail at any time. You must test the unit weekly to ensure

your continued protection. Smoke Alarms cannot prevent or extinguish fires. They are not a

substitute for property or life insurance.

Smoke Alarms have a limited life. The unit should be replaced immediately if it is not

operating properly. You should always replace a Smoke Alarm after 10 years from date of

purchase. Write the purchase date on the space provided on back of unit.

ABOUT SMOKE ALARMS

Battery (DC) operated Smoke Alarms: Provide protection even when electricity fails,

provided the batteries are fresh and correctly installed. Units are easy to install, and do not

require professional installation. However, they do not provide interconnected functionality.

AC powered Smoke Alarms: Can be interconnected so if one unit senses smoke, all

units alarm. They do not operate if electricity fails. AC with battery (DC) back-up: will

operate if electricity fails, provided the batteries are fresh and correctly installed. AC and

AC/DC units must be installed by a qualified electrician.

Wireless Interconnected Alarms: Offer the same interconnected functionality as with

hardwired alarms, without wires. Units are easy to install and do not require professional

installation. They provide protection even when electricity fails, provided the batteries are

fresh and correctly installed.

Smoke Alarms for Solar or Wind Energy users and battery backup power systems:

AC powered Smoke Alarms should only be operated with true or pure sine wave inverters.

Operating this Smoke Alarm with most battery-powered UPS (uninterruptible power supply)

products or square wave or “quasi sine wave” inverters will damage the Alarm. If you are

not sure about your inverter or UPS type, please consult with the manufacturer to verify.

Smoke Alarms for the hearing impaired: Special purpose Smoke Alarms should be

installed for the hearing impaired. They include a visual alarm and an audible alarm horn,

and meet the requirements of the Americans With Disabilities Act. These units can be

interconnected so if one unit senses smoke, all units alarm.

Smoke alarms are not to be used with detector guards unless the combination has

been evaluated and found suitable for that purpose.

All these Smoke Alarms are designed to provide early warning of fires if located, installed and

cared for as described in the user’s manual, and if smoke reaches the Alarm. If you are unsure

which type of unit to install, refer to NFPA (National Fire Protection Association) 72 (National

Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National Fire Protection

Association, One Batterymarch Park, Quincy, MA 02269-9101.

Local building codes may

also require specific units in new construction or in different areas of the home.

LOCATIONS TO AVOID FOR SMOKE ALARMS, Continued

LOCATIONS TO AVOID FOR SMOKE ALARMS

For best performance, AVOID installing Smoke Alarms in these areas:

• Where combustion particles are produced. Combustion particles form when something

burns. Areas to avoid include poorly ventilated kitchens, garages, and furnace rooms.

Keep units at least 20 feet (6 meters) from the sources of combustion particles (stove,

furnace, water heater, space heater) if possible. In areas where a 20-foot (6 meter)

distance is not possible – in modular, mobile, or smaller homes, for example – it is

recommended the Smoke Alarm be placed as far from these fuel-burning sources as

possible. The placement recommendations are intended to keep these Alarms at a

reasonable distance from a fuel-burning source, and thus reduce “unwanted” alarms.

Unwanted alarms can occur if a Smoke Alarm is placed directly next to a fuel-burning

source. Ventilate these areas as much as possible.
